Alright, Rusty here, takin' a look at what's ahead for the next couple weeks. Started off quiet, but the real meat is waitin' for the patient ones.
Water temp's about 74°, right where it should be for the time of year.
Friday afternoon is a total loss. A tiny 1ft south swell with a real long 18-second period, but it's toast from a 20 km/h onshore wind. We got a few empty days before anythin' worthwhile.
Saturday, July 4th morning is our first real shot. A clean 5ft swell from the SSW, 10-second period, and glassy conditions. That's the wind you dream about. The wave energy is moderate (961). Not the big show, but a great start.
Sunday, July 5th bumps up over 8ft from the same direction, with a 12-second period. That's a heap of power (1517 energy), but it's onshore wind and light rain. That's expert territory for certain.
Now for the standouts. You wanna lock in Monday morning, July 6th and Saturday morning, July 18th.
Monday morning, July 6th at Jaconé is a prime pick. A clean 6ft swell from the south with an 11-second period, and a light ENE breeze blowin' cross-offshore. That's gonna give us smooth, lined-up waves. The energy is solid (961). Perfect for intermediates who want a good session without gettin' worked.
Then, for the big one, Saturday morning, July 18th. A long way out, so treat it as a possibility that could shift, but it looks *perfect*. A 5ft groundswell from the south, with an 18-second period. That's an absolute pulse of power (1476 energy). And the wind? Gentle offshore from the northeast. Gentle offshore and clean. This is for experienced surfers, the kind of day you clear your schedule for.
In between, there's some good smaller windows. Thursday, July 10th morning has a clean 4ft south swell with offshore ENE wind. A nice sneaky one. Saturday, July 11th morning shows a 4ft swell from the SE with a 12-second period and light cross-offshore wind. Good fun, but watch for crowds – it's noted as 'sometimes' busy. Monday, July 13th morning is another tidy one: 4ft from the south, 11-second period, light cross-off wind, clean.
The week after that gets a bit messy with onshore wind. A couple of small clean windows appear on Wednesday, July 15th with a 3ft SSE swell and offshore NE wind, and a real quirky one on Friday afternoon, July 17th – a tiny 2ft south swell with a massive 19-second period (526 energy). Weird stuff, might work on a longboard.
Bottom line: don't miss Monday the 6th, and keep your eye on that Saturday the 18th – that one's got the potential to be the session of the year if the wind stays true.
Rusty, out.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
